Encircling the entire island of Bonaire—and the neighboring islet of Klein Bonaire—Bonaire National Marine Park is home to some of the best snorkeling and diving you’ll ever do. Thanks to long-standing protective measures (dive-site moorings that preclude damage from anchors being dropped nearby, for example), the coral and fish here are some of the healthiest in the region, so expect a profusion of marine life, whether in the form of tiny sea horses, massive morays, or a zillion creatures in between.
